Suunto Nautic User Guide
Example - Single gas mode
The following example shows a no-decompression dive in Single gas mode with Air and a Suunto Tank POD.
Surface screen:
We recommend starting your dive from the surface view to verify all key settings before descending. Check that your gas and algorithm settings are correct, your device has a GPS signal, and you have sufficient battery and tank pressure (if linked to a Suunto Tank POD). Make sure you are diving with the correct gas mixture and that you understand the maximum operating depth (MOD) of the active gas.
If the Suunto Tank POD battery is low, or if the tank pressure is below the safe limit, a warning will be shown on the screen.
Once descending over 10 m, a safety stop indication will appear in the switch window, indicating a safety stop ceiling of 3 m. No deco time shows > 99, meaning the maximum time you can spend at this depth is greater than 99 min.
Once you continue the descent, the No deco time will show a smaller value. No deco time is always in minutes.
If your No deco time reaches 5 min, a yellow caution alarm will be triggered. When ascending and the No deco value is increased, the alarm will be resolved. You can also mute the alarm with any button press. Continuing to stay at deeper depths despite the No deco alarm can cause decompression obligation. Do not dive decompression dives unless you’ve sufficient training.
You can set your own tank pressure alarms to help you keep track of critical limits, like turn pressure. If set, Suunto Nautic alerts you when reaching 100 bar (1450 psi).
When you are between 2.4 and 6 m (7.9 and 20 ft), a safety stop timer will appear and count down until the suggested stop. Once the stop is performed, a Stop done notification will appear.
